887-070-542-807

Edgeboard Connectors Overview

The EDAC Inc. 887-070-542-807 is a high-temperature card edge connector from the 887 series, designed for reliable signal transmission in demanding environments. It features a dual-edge female configuration with 70 positions and a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated contacts on a copper alloy base, housed in a black Polyphenylene Sulfide (PPS) insulator rated UL 94V-0. It supports board thicknesses between 0.054 and 0.070 inches, operates within -40°C to +125°C, and offers a 3A current rating with 5 GOhms insulation resistance.

Edgeboard Connectors Feature Summary

• Gold-plated terminals ensuring low contact impedance
• Multiple mounting options including panel mount configurations

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• Telecommunications equipment interfaces
• Medical device internal connections
• Energy sector instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact pin style and mounting ear variations. Ensure the target PCB thickness falls within the specified 0.054 to 0.070 inch range for proper retention force. Confirm that the application environment does not exceed the maximum operating temperature of 125°C. Cross-reference the part number with authorized distributors to ensure genuine EDAC Inc. sourcing.

Edgeboard Connectors Selection Notes

Select this component when high thermal endurance and durable mechanical retention are required for double-sided edge cards. The 887 series distinguishes itself with a taller insulator profile compared to standard series, providing deeper slot engagement. Choose this model over the 837 series if Polyphenylene Sulfide material properties are preferred for higher heat resistance. Ensure the chosen variant matches the necessary solder tail style for the intended PCB assembly process.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 887 High Temperature Series, which is engineered for superior performance in harsh conditions. The series offers various terminal styles and mounting configurations to accommodate diverse mechanical constraints. It is widely utilized in sectors where standard connectors may fail due to thermal stress or vibration. The 887 series provides a balance of electrical reliability and mechanical durability for critical interconnect applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 887 series variants with matching position counts and pitch. Verify compatibility with existing PCB footprints before swapping models. Generic replacements must match the 0.156-inch pitch and dual-edge female specification. Ensure any alternative maintains the same thermal rating and material composition for equivalent performance.
